Hybrid tea rose plant named `JACnepal`

ABSTRACT

A hybrid tea rose plant having vigorous, upright growth; large flowers produced one per stem; mildew and rust resistant foliage; a blend of colors in the flower; and stems long enough for cutting.

The present invention relates to a new and distinct variety of rose plant of the hybrid tea class which was originated by me by crossing JACyap (not patented), with MACnewye (U.S. Plant Pat. No. 5,428).

The primary objective of this breeding was to produce a new rose variety having vigorous, upright growth; large flowers produced one per stem; disease resistant foliage; a blend of colors in the flower; and stems long enough for cutting. The objective was substantially achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics that are otustanding in the new variety and that distinguish it from its parents, as well as from all other varieties of which I am aware:

1. High centered large flowers;

2. Long stems;

3. Blooms one flower per stem;

4. Dark green, glossy, disease resistant foliage;

5. Vigorous, upright growing plant;

6. Flowers that exhibit a blend of colors.

JACnepal is a vigorous, upright, well-branched garden hybrid tea. It produces long-stemmed, large-flowered roses that are a bend of colors. Foliage is dark green, glossy, and very disease resistant.

Asexual reproduction of this new variety by budding, as performed at Wasco, Calif., shows that the foregoing and all other characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying illustration shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of my new rose cultivar with color descriptions using terminology in accordance with The Royal Horticultural Society (London) Colour Chart, except where ordinary dictionary significance of color is indicted.

Color.--The upper sides of the petals are Orange-White Group 159D with petal edges Red Group 45D. The reverse sides of the petals are Orange-White Group 159D with petal edges Red Group 45D. The base of each petal has on both surfaces a 1/4×1/4" Yellow Group 12B half moon at the point of attachment. The major color on the upper sides is Orange-White Group 159D.

Variegations.--None.

Discoloration.--At the end of the first day: No change. At the end of the third day: No change. By day five or six, on the plant, there is a fading of color on the petal edges to Red Group 48B.

Fragrance.--Moderate; spicy.

Petals:

Texture.--Thick.

Shape.--Round.

Form.--Tips slightly recurved.
